ABSTRACT

Unaided communication refers to techniques that utilize body parts and movements, usually the arms and hands (e.g., gestures and sign sys­ tems). Unaided communication can be either the primary mode or a sup­ plemental technique of an augmentative communication system. Aided communication refers to techniques that utilize a physical object or de­ vice (e.g., manual board, electronic device). Current practice in the se­ lection of an augmentative communication system emphasizes use of sev­ eral augmentative techniques with a given individual to provide a means of communication in as many settings as possible, with and without equipment. Such a system may include an electronic device, a manual board, and a gesture/sign system.
